Chemical Structure
Description
As a certified reference material (CRM), (1,1-dioxo-1λ⁶-thian-3-yl)methanesulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies (1,1-dioxo-1λ⁶-thian-3-yl)methanesulfonyl chloride (CAS 1781507-54-7), a certified reference material (molecular formula C6H11ClO4S2, MW 246.73 g/mol) for analytical method development and quality control.
(1,1-dioxo-1λ⁶-thian-3-yl)methanesulfonyl chloride (C6H11ClO4S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
